      drm/radeon/kms: add support for new fault callback V7 · 0a2d50e3
      由 Jerome Glisse 提交于 
      This add the support for the new fault callback and also the
infrastructure for supporting unmappable VRAM.

V2 validate BO with no_wait = true
V3 don't derefence bo->mem.mm_node as it's not NULL only for
   VRAM or GTT
V4 update to splitted no_wait ttm change
V5 update to new balanced io_mem_reserve/free change
V6 callback is responsible for iomapping memory
V7 move back iomapping to ttm

      drm/ttm: ttm_fault callback to allow driver to handle bo placement V6 · 82c5da6b
      由 Jerome Glisse 提交于 
      On fault the driver is given the opportunity to perform any operation
it sees fit in order to place the buffer into a CPU visible area of
memory. This patch doesn't break TTM users, nouveau, vmwgfx and radeon
should keep working properly. Future patch will take advantage of this
infrastructure and remove the old path from TTM once driver are
converted.

V2 return VM_FAULT_NOPAGE if callback return -EBUSY or -ERESTARTSYS
V3 balance io_mem_reserve and io_mem_free call, fault_reserve_notify
   is responsible to perform any necessary task for mapping to succeed
V4 minor cleanup, atomic_t -> bool as member is protected by reserve
   mecanism from concurent access
V5 the callback is now responsible for iomapping the bo and providing
   a virtual address this simplify TTM and will allow to get rid of
   TTM_MEMTYPE_FLAG_NEEDS_IOREMAP
V6 use the bus addr data to decide to ioremap or this isn't needed
   but we don't necesarily need to ioremap in the callback but still
   allow driver to use static mapping
